增强现实（AR）中正在进行的研究问题是改进跟踪和显示技术，以最大限度地减少注册错误。然而，完美的配准对于用户理解增强的意图并不总是必要的。本文描述了一个实验的结果，以评估图形上下文的影响，在乐高积木放置任务时，图形位于任务区之外。比较了四种情况：完全注册的AR;未注册的AR;具有在视场中总是可见的图形的平视显示器（HUD）;以及具有在视场中不总是可见的图形的HUD。该实验的结果表明，注册AR优于非注册AR和HUD上显示的图形。结果还表明，非注册AR与HUD相比没有任何显着的性能优势，但被评为侵入性较低，并且可以防止非注册图形扰乱任务空间。
An ongoing research problem in Augmented Reality (AR) is to improve tracking and display technology in order to minimize registration errors. However, perfect registration is not always necessary for users to understand the intent of an augmentation. This paper describes the results of an experiment to evaluate the effects of graphical context in a Lego block placement task when the graphics are located outside of the task area. Four conditions were compared: fully registered AR; non-registered AR; a heads-up display (HUD) with the graphics always visible in the field of view; and a HUD with the graphics not always visible in the field of view. The results of this experiment indicated that registered AR outperforms both non-registered AR and graphics displayed on a HUD. The results also indicated that non-registered AR does not offer any significant performance advantages over a HUD, but is rated as less intrusive and can keep non-registered graphics from cluttering the task space.
